Electric control unit

Abstract

These embodiments relates to an electric control unit including a circuit board that is provided in a housing, a damper including a frame member that is formed in correspondence with a frame of the circuit board and is combined with an upper face of the circuit board and a damping member combined with an upper face of the frame member, and a housing cover that is supported at the damping member and is combined with the housing and prevent generation of noise due to vibrations of the housing cover.

What is claimed is: 
     
       1. An electric control unit comprising:
 a circuit board that is provided in a housing; 
 a damper including: a frame member that is formed in correspondence with a frame of the circuit board, the frame member contacting an upper face of the circuit board, and a damping member spaced apart from an upper face of the circuit board so that the frame member is disposed between the circuit board and the damping member; and 
 a housing cover that is supported at the damping member and is combined with the housing, 
 wherein the damping member includes a plurality of peak parts and trough parts formed on an upper face of the damping member, 
 wherein the circuit board includes a combination hole vertically passing through the circuit board, and the frame member includes a combination part that is formed to protrude from a lower face of the frame member and is inserted into the combination hole, and 
 wherein the combination part includes a small-diameter part supported on an inner circumferential face of the combination hole and a large-diameter part protruding from the combination hole to a lower side. 
 
     
     
       2. The electric control unit according to  claim 1 , wherein two or more combination holes are provided with being separated from each other, and the combination parts are provided at positions corresponding to the combination holes. 
     
     
       3. The electric control unit according to  claim 1 , wherein the combination part includes an incision part that divides the small-diameter part and the large-diameter part. 
     
     
       4. The electric control unit according to  claim 3 , wherein the large-diameter part is formed to have a tapered lower end. 
     
     
       5. The electric control unit according to  claim 1 , wherein the frame member includes two or more mount parts with which the damping member is combined and a connecting part connecting the mount parts. 
     
     
       6. The electric control unit according to  claim 5 , wherein the mount parts are formed to have a width larger than that of the connecting part. 
     
     
       7. The electric control unit according to  claim 5 , wherein the mount parts are arranged at positions facing each other with reference to the center of the frame member. 
     
     
       8. An electric control unit comprising:
 a circuit board that is provided in a housing; 
 a damper including: a frame member that is formed in correspondence with a frame of the circuit board, the frame member contacting an upper face of the circuit board, and a damping member spaced apart from an upper face of the circuit board so that the frame member is disposed between the circuit board and the damping member; and 
 a housing cover that is supported at the damping member and is combined with the housing, 
 wherein the damping member includes a plurality of protrusions formed on an upper face of the damping member, 
 wherein the circuit board includes a combination hole vertically passing through the circuit board, and the frame member includes a combination part that is formed to protrude from a lower face of the frame member and is inserted into the combination hole, and 
 wherein the combination part includes a small-diameter part supported on an inner circumferential face of the combination hole and a large-diameter part protruding from the combination hole to a lower side.
